A Joomla 1.5 installation has been set up and the component nBill is installed successfully. Now, a payment gateway has to be set up to make it work.
For more information on nBill, see http://www.nbill.co.uk/
The payment gateway is called 123Betalingsgateway and it's from http://curanet.dk/
There is no English documentation for this gateway.
A programmer is needed to integrate the payment gateway 123Betalingsgateway into nBill to allow for transactions to go through successfully.
Previous experience with nBill is an advantage, though not required.
